IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its components
and cause the sprinkler to fail to
operate in a fire situation or cause it
to operate prematurely.
tal adjustment from the flush mounting
surface position. The adjustment pro-
vided by the Recessed Escutcheon re-
duces the accuracy to which the pipe
nipples to the sprinklers must be cut.
The Series LFII (TY4334) has been de-
signed with heat sensitivity and water
distribution characteristics proven to
help in the control of residential fires
and to improve the chance for occu-
pants to escape or be evacuated.

General
Description
The Tyco®Rapid Response™Series
LFII (TY4334) Residential Horizontal
Sidewall Sprinklers are decorative, fast
response, frangible bulb sprinklers de-
signed for use in residential occupan-
cies such as homes, apartments, dor-
mitories, and hotels. When enhanced
flow characteristics for residential por-
tions of any occupancy per NFPA 13 is
the major consideration, the Series LFII
(TY4334) should be the first choice.
When higher flow demands are re-
quired for residential sprinklers used
in an NFPA 13 design, the large 5.8 K-
factor of the Series LFII (TY4334) is an
attractive choice. Although mostly in-
tended where residential sprinklers are
to be used in an NFPA 13 design, the
Series LFII (TY4334) can also be used
in wet pipe residential sprinkler sys-
tems for one- and two-family dwell-
ings and mobile homes per NFPA 13D,
and wet pipe residential sprinkler sys-
tems for residential occupancies up to
and including four stories in height per
NFPA 13R.
The recessed version of the Series LFII
(TY4334) is intended for use in areas
with finished walls. It employs a two-
piece Style 20 Recessed Escutcheon.
The Recessed Escutcheon provides
1/4 inch (6,4 mm) of recessed adjust-
ment or up to 1/2 inch (12,7 mm) of to-

Operation
The glass bulb contains a fluid which
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and water to flow.
Design Criteria
UL AND C-UL LISTING CRITERIA
The Series LFII (TY4334) Residential
Horizontal Sidewall Sprinklers are UL
and C-UL Listed for installation in ac-
cordance with the following criteria.
NOTE
When conditions exist that are outside
the scope of the provided criteria, re-
fer to the Residential Sprinkler Design
Guide TFP490 for the manufacturer’s
recommendations that may be ac-
ceptable to the local Authority Having
Jurisdiction.
System Type. Only wet pipe systems
may be utilized.
Hydraulic Design. The minimum re-
quired sprinkler flow rate for systems
designed to NFPA 13D or NFPA 13R
are given in Table A as a function of
temperature rating and the maximum
allowable coverage areas. The sprin-
kler flow rate is the minimum required
discharge from each of the total num-
ber of “design sprinklers” as specified
in NFPA 13D or NFPA 13R.
For systems designed to NFPA 13, the
number of design sprinklers is to be
the four most hydraulically demanding
sprinklers. The minimum required dis-
charge from each of the four sprinklers
is to be the greater of the following:
• The flow rates given in Table A for
NFPA 13D and 13R as a function of
temperature rating and the maximum
allowable coverage area.
• A minimum discharge of 0.1 gpm/
sq. ft. over the “design area” com-
prised of the four most hydraulically
demanding sprinklers for the actual
coverage areas being protected by
the four sprinklers.
Example No. 1: A corridor being pro-
tected is 8 ft. wide; consequently, an
actual coverage area of 8 ft. x 20 ft.
is being contemplated. Based on us-
ing the LFII (TY4334) Residential Hor-
izontal Sidewall Sprinklers, the flow
rate provided in Table A for a 16 ft x
20 ft. coverage area is 29 GPM. How-
ever based on minimum discharge of
0.1 gpm/sq. ft. the flow rate would be
16 GPM. In this case a minimum flow
rate of 29 GPM for this design sprin-
kler must be utilized.
Example No. 2: The room being pro-
tected is 16 x 16 ft.. Based on using
the LFII (TY4334) Residential Hori-
zontal Sidewall Sprinklers, the flow
rate provided in Table A for a 16 ft. x
16 ft. coverage area is 21 GPM. How-
ever based on minimum discharge of
0.1 gpm/sq. ft. the flow rate would be
26 GPM. In this case a minimum flow
rate of 26 GPM for this design sprin-
kler must be utilized.
Obstruction To Water Distribution.
Locations of sprinklers are to be in ac-
cordance with the obstruction rules of
NFPA 13 for residential sprinklers.
Operational Sensitivity. The sprin-
klers are to be installed with an end-of-
deflector-boss to wall distance of 1-3/8
to 6 inches or in the recessed position
using only the Style 20 Recessed Es-
cutcheon as shown in Figure 2.
In addition the top-of-deflector-to-
ceiling distance is to be within the
range (Ref. Table A) being hydraulically
calculated.
Sprinkler Spacing. The minimum
spacing between sprinklers is 8 feet
(2,4 m). The maximum spacing be-
tween sprinklers can not exceed the
width of the coverage area (Ref. Table
A) being hydraulically calculated (e.g.,
maximum 12 feet for a 12 ft. x 12 ft.
coverage area, or 16 feet for a 16 ft. x
20 ft. coverage area).
FM APPROVAL CRITERIA
The Series LFII (TY4334) Residen-
tial Horizontal Sidewall Sprinklers are
FM Approved for installation in accor-
dance with the applicable Factory Mu-
tual Loss Prevention Data Sheet. Cri-
teria provided by FM may differ for UL
and/or NFPA, therefore the designer
should review and become familiar
with Factory Mutual requirements be-
fore proceeding with design
NOTE
When conditions exist that are outside
the scope of the provided criteria, re-
fer to the Residential Sprinkler Design
Guide TFP490 for the manufacturer’s
recommendations that may be ac-
ceptable to the local Authority Having
Jurisdiction.
The following information pertaining to
System Type, Hydraulic Design, and
Sprinkler spacing are provided for ref-
erence and are not intended to provide
complete installation criteria as pro-
vided in the applicable Factory Mutual
Loss Prevention Data Sheet.
System Type. Only wet pipe systems
may be utilized.
Hydraulic Design. The number of de-
sign sprinklers is to be the four most
hydraulically demanding sprinklers.
The minimum required discharge from
each of the four sprinklers is to be
greater than the following:
• The flow rates given in Table B as a
function of the maximum allowable
coverage area.
• A minimum discharge of 0.1 gpm/
sq. ft. over the “design area” com-
prised of the four most hydraulically
demanding sprinklers for the actual
coverage areas being protected by
the four sprinklers.
Example No. 1: A corridor being pro-
tected is 8 ft. wide; consequently, an
actual coverage area of 8 ft. x 20 ft.
is being contemplated. Based on us-
ing the LFII (TY4334) Residential Hor-
izontal Sidewall Sprinklers, the flow
rate provided in Table B for a 16 ft x
20 ft. coverage area is 32 GPM. How-
ever based on minimum discharge of
0.1 gpm/sq. ft. the flow rate would be
16 GPM. In this case a minimum flow
rate of 32 GPM for this design sprin-
kler must be utilized.
Example No. 2: The room being pro-
tected is 16 x 16 ft.. Based on using
the LFII (TY4334) Residential Hori-
zontal Sidewall Sprinklers, the flow
rate provided in Table B for a 16 ft x
16 ft. coverage area is 24 GPM. How-
ever based on minimum discharge of
0.1 gpm/sq. ft. the flow rate would be
26 GPM. In this case a minimum flow
rate of 26 GPM for this design sprin-
kler must be utilized.

Sprinkler Spacing. The minimum
spacing between sprinklers is 8 feet
(2,4 m). The maximum spacing be-
tween sprinklers can not exceed the
width of the coverage area (Ref. Table
B) being hydraulically calculated (e.g.,
maximum 12 feet for a 12 ft. x 12 ft.
coverage area, or 16 feet for a 16 ft. x
20 ft. coverage area).
Installation
The Series LFII (TY4334) must be in-
stalled in accordance with the follow-
ing instructions:
NOTES
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bub-
ble should be present. The diameter
of the air bubble is approximately 1/16
inch (1,6 mm).
A 1/2 inch NPT sprinkler joint should
be obtained with a minimum to maxi-
mum torque of 7 to 14 ft. lbs. (9,5 to
19,0 Nm). Higher levels of torque may
distort the sprinkler inlet with conse-
quent leakage or impairment of the
sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
The Series LFII Horizontal Sidewall
Sprinklers must be installed in accor-
dance with the following instructions.
Step 1. Horizontal sidewall sprinklers
are to be installed in the horizontal po-
sition with their centerline of waterway
perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the Deflector is to face towards the
ceiling with the front edge of the De-
flector parallel to the ceiling.
Step 2. With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Ref. Figure 3).
With reference to Figure 1, the W-Type
6 Sprinkler Wrench is to be applied to
the wrench flats.
The Series LFII Recessed Horizontal
Sidewall Sprinklers must be installed
in accordance with the following
instructions.
Step A. Recessed horizontal sidewall
sprinklers are to be installed in the hor-
izontal position with their centerline of
waterway perpendicular to the back
wall and parallel to the ceiling. The
word “TOP” on the Deflector is to face
towards the ceiling.
Step B. After installing the Style 20
Mounting Plate over the sprinkler
threads and with pipe thread seal-
ant applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step C. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 7
Recessed Sprinkler Wrench (Ref. Fig-
ure 4). With reference to Figure 1, the
W-Type 7 Recessed Sprinkler Wrench
is to be applied to the sprinkler wrench
flats.
Step D. After the wall has been in-
stalled or the finish coat has been ap-
plied, slide on the Style 20 Closure
over the Series LFII Sprinkler and push
the Closure over the Mounting Plate
until its flange comes in contact with
the wall.

Care and
Maintenance
The Tyco®Rapid Response™ Series
LFII (TY4334) must be maintained and
serviced in accordance with the fol-
lowing instructions:
NOTES
Absence of an Escutcheon Plate may
delay the sprinkler operation in a fire
situation.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
which it controls, permission to shut
down the affected fire protection sys-
tem must be obtained from the prop-
er authorities and all personnel who
may be affected by this action must be
notified.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory. Mod-
ified sprinklers must be replaced to
corrosive products of combustion, but
have not operated, should be replaced
if they can not be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers- before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed. Also, replace any sprinkler that
has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section).
The owner is responsible for the in-
spection, testing, and maintenance of
